The estimate-talk-estimate approach (ETE), commonly known as the Delphi method, is a structured and qualitative method of forecasting that involves asking a group of experts a series of questions to elicit their thoughts. The Delphi method depends on experts who are educated about a certain subject in order for them to make predictions about the outcomes of hypothetical future scenarios, assess the possibility of an event, or come to an agreement on a given subject.
The Delphi method approach entails a number of rounds of written questionnaires that invite expert input. Following the completion of each set of questionnaires by the experts, the facilitator compiles all the responses and provides a summary report of the results to each expert. The experts next go over the summary report and decide whether they concur with the other experts' responses or not.
The experts then complete a second questionnaire that allows them to express updated perspectives based on what they have learned from the summary report. The estimate-talk-estimate approach (ETE), commonly known as the Delphi method, is a structured and qualitative method of forecasting that involves asking a group When a forecast consensus is reached, the Delphi process is finished.
